Abstract
Microscale thin-film thermocouples (TFTCs) which can be fabricated usi ng existing microelectronics technology on the surfaces of electronic devices with film thicknesses as small as tens of angstroms, have smal ler thermoelectric potential compared to thick-film Eases. The qualita tive characteristics of TFTCs, which have not yet been modeled success fully, have been analyzed based on the model of distributed electric p otential across the interface of two metals. The steady-stale solution of the electron distribution and the electric potential distribution by solving the one-dimensional Schrodinger equation and the Poisson eq uation simultaneously show the decrease in the thermoelectric potentia l quantitatively.
